Early September 2026 has brought only 0.18–0.36 inches of precipitation to Seattle through the first six days, well below the 1.6-inch climatological normal. Short-range forecasts from NOAA and local models indicate mostly dry conditions with isolated light drizzle or showers totaling under 0.5 inches over the next 7–10 days, keeping cumulative amounts low. September marks the seasonal transition toward wetter fall patterns, yet the absence of strong atmospheric rivers or persistent onshore flow so far supports trader consensus around sub-1-inch or near-normal 1.5–2-inch outcomes. Updated model runs and any late-month storm tracks will be key variables influencing final totals.

This market will resolve according to the total precipitation in inches in Seattle between September 1 and September 30, 2026, 11:59PM ET according to the National Oceanic and Atmospheric Administration (NOAA).
If the reported data falls exactly between two brackets, this market will resolve to the higher bracket.
The resolution source for this market will be NOAA, specifically the figure for September 2026 when the "Monthly summarized data" for "Seattle City Area" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=sew link once that figure is finalized for the whole month of September 2026.
If the relevant data is not available by December 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.
The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Early September 2026 has brought only 0.18–0.36 inches of precipitation to Seattle through the first six days, well below the 1.6-inch climatological normal.
